IMPROVEMENT IN LAMP-BURNERS.

Specication forming part of Letters Patent No. 179,685, dated July 11, 1876; application filed June 8, 1876.

To all whom t may concern:

Be it known that I, FERDINAND DAMGKE, of St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and Improved Lamp-Burner, of which the following is a specification:

This invention rela-tes to an improvement on the class ot' lamp-burners that are provided with annular wick-tubes adapted to receive cylindrical wicks.

The invention has for its object to increase the illuminating capacity of such burner by increasing the diameter of the flame; and consists in applying', above the burner, aremovable horizontal disk, of a diameter larger than that of the wick-tube, in the manner herein after more fully described.

In the accompanying drawing, Figure l is a side view, partly in section, ot' myimproved burner. Fig. 2 is a top view of the same.

The letter A represents a burner ot' suitable construction, provided with an annular wicktnbe, a, to receive a cylindrical wick, b, in the Above this burner A is applied a disk, B, made of metal orequivalent material, and ot a diameter considerably larg er than that of the wick-tube a, so as to project beyond the circumference ot' the same. The disk B is held in place above the burner by a central downwardly-projecting stem, c, to the lower end of which are applied spring-jaws d d, which bear against the inner side ot' the wick-tube a, as clearly shown in Fig. 1.

By this construction the disk B may be raised or lowered to suit convenience, and may, also, be entirely removed from the burner, it' desired; but in place of the spring-jaws d d other suitable fastening devices may be substituted for attaching the disk B to, and holdingA it above, the burner.

By the use of the disk B above the burner A I cause the llame to impinge on and strike the lower side of the disk, then to assume a horizontal direction until it reaches the circumference of the disk, whereupon it turns upward and burns around the disk. Now, as the diameter of this disk B is much larger than that ofthe wick-tube ct-preferably, about twice as large-.the diameter and the surface ot' the flame are greatly increased without i'ncreasing the size of the wick, or adding to the` consumption ot' fuel.

Itis well known that the amount ot" light produced by a llame is proportionate to the surface of' the same, and not to its thickness. l11t`act,a thin sheet of Haine will yield as much light as a thicker one having the same areaof surface.

In the annular burners heretoforeused, the dia-meter ot' the flame was never larger than that ofthe wick-tube, and the surface and consequent lighting capacity of the Haine was therefore comparatively small. By increasing the diameter and surface ot' the flame by the disk B, I increase its lighting capacity withont increasing the consumption ot' fuel or otherwise changing the structure of the burner. rlhe disk B may also be applied to other burners than those having wicks, such as argand gas-burners.

I claim as my invention- The disk B, provided with the stein c and springjaws d d, and combined with the burner A, substantially as herein shown and described.
